Warning: Ensure the pump is turned off before starting the cleaning process.

Cover at the side of the coolant pump removed

Coolant drawn out of the tank by the pump

Coolant tank pulled out to the right until the pump protrudes from the side cover

Coolant tank pulled out to the front

Inside of the coolant tank cleaned

Coolant tank reinstalled correctly

Caution: The coolant tank must not protrude from the front rail. If the coolant tank is not installed correctly, coolant will leak.

NOTICE! The machine should be completely and correctly lubricated in strict adherence to the directions in the Lubrication Chart in the following page.

Is the specified lubrication oil used?

Is the amount of lubricating oil and its discharge condition checked everyday?

Note 1: We do not have any experience in using the oils other than those indicated by an asterisk(*). Selection should thus be made from them. Because slide-way lubricating oil contains additives such as extreme-pressure additive, it could incur variety of troubles if reacting with other oils or coolant. Therefore, pay special attention to the use of slide way lubricating oil.

Note 2: As for service point or amount of lubricating oil of the machine, refer to the Instruction Manual of respective machine models.

Note 3 : Lubricating oil used in common with coolant or lubricating oil used in common with hydraulic oil might cause corrosion of lubrication unit or turbidness of oils to result in lubrication failure, which, in turn, leads to damages on the slideway surface or ball screw. (We take no responsibility for the troubles caused by using the lubricating oil which is not our recommendation.)

Note 4: As for oil replenishment for the optional accessories such as special chucks or chip conveyor, refer to the Special Instruction Manual supplied with individual accessories.

Note 5: When slideway lubricating oil mixed with coolant and some trouble appears, contact your local DOOSAN Infracore representatives. They have optional accessories such as oil skimmer.

- Checking for sounds of reaction during sensor contact

- Removing any chips from the coolant collector

- Checking the degree of dirtiness of the coolant and if necessary, replacing;

Checking and adjusting the bed level using a level

1. Adjusting V-belt Between The Spindle and Main Motor

• When the PK-belts are worn or loosen after using for a long period, it is advisable to tension them or replace them with new ones.

Adjust the belt tension as below procedure

1) Loosen the fastening bolts (1) of motor bracket.

2) Loosen the nut (2) under the adjusting block.

3) Secure the adjusting bolt (3) slowly.

4) Check the amount of deflection value (d) of PK-belt with tension (F1) as above table.

5) After getting the set value (5), secure the nut (2).
